What is the equivalent mass of H3PO3?
The molecular mass of H3PO3 is 82 . Its equivalent mass, if it is completely neutralised, is.
How do you calculate equivalent weight from molecular weight?
Equivalent Weight = Molecular weight/ Valency Also, read: Chemical Reaction.
What is the equivalent weight of H 3 PO 2?
The number of oxidation shifts is from 1 to +3. Therefore, for 2 molecules of H3PO2, the electron given is 2e-. Therefore, 4 electrons are used . In complete, thus, 4e- are exchanged.
What is the N factor for H3PO3?
Therefore, since H3PO3 has only two H attached to O, its n-factor is 2 and not 3.
What is the molecular weight of H3PO2^+1→PH3^-3?
H 3 PO2 → pH 3 + H 3 PO 3 In first we take h3po2^+1→ph3^-3 thenH3po2^+1→h3po3^+3Mole molecular weight of h 3 PO 2 equals to 3 + 31 + 48 =82 Equivalent weight equals to 82 / 1- (-3)+82/1-3 =82/4+82/2 =61.5 Please find below the solution to your problem. change in oxidation number is from 1 to -3.
What is the equivalent weight of the solution?
An equivalent weight of a solution is defined as the molecular weight of the solute divided by the valence of the solute. Equivalent weight is used for predicting the mass of a substance that reacts with one atom of hydrogen in an acid-base analysis like in titration. The given reaction is: Ca (OH) 2 + H 3 PO 4 → CaHPO 4 + 2H 2 O
What is the n-factor of H3PO2 to PH3?
Now, find the n-factor (total change in oxidation number per molecule) and then equivalent mass = molar mass/n-factor. So, when H3PO2 changes into PH3, oxidation state of phosphorous changes from +1 to -3 so as n-factor is 4. Also when H3PO2 changes into H3PO4, oxidation state of phosphorous changes from +1 to +5 so as n-factor is again 4.
What is the equivalent mass of an acid in molar mass?
, is a dibasic (diprotic) acid. Its basicity is 2. Therefore, its equivalent mass = Molecular mass/2 = 82/2 = 41. Was this answer helpful?
